CONCRETE iivsnnr.

Application led November 10, 1926.V Serial No. 147,596. 4 i

My invention relates to concreteinserts, such as are intended to be setin concrete floors, walls, ceilings, and the like to facilitate theattachment of various articles or devices.

One of the objects of the invention is to pro.

vide a simple, practical and advantageous constructionor form ofconcrete insert.

Another object of the inventionis to arrange for the ready attachment ofthe bolt or rod or pipe or other device in a simple and easy manner.

Another object of the invention is to permit the bolt or rod or pipeafter connection with the insert, to be readily adjusted to per mitconnection with other parts or devices and particularly to permit it tobe turned or rotated so as to make screw connectionwith another threadedpart, without unscrewingV concrete inserthaving certainy of thefeaturesof construction-and operation herein set forth. l

In the accompanying drawings:

Fig. 1 is av view showing a concrete insert embodying my invention andalso a portion of the device of the wall orrceiling in which the sameisV imbedded, and also showing the temporary or false work used inconnection with the wall or ceiling. v

Fig. 3 is a ing upward. 1

Figs. 4 and 5 varecross sectionstakeny on lines .11-4'and 5-5respectively inl Fig. 1.

In the drawings Il show a concrete insert'1' preferably made of metaland so designed that it may be cast. This insert is shown imbedded inconcrete material A, the false work B being also shown. Y

The insert 1 is of generallyelongated form having an upper chamber orrecess 2 and a lower chamber or recess 3. The top 4 prefer- 'clined toprovide an inclinedchamberl in f vwhich the. bolt 5 or similar elementmaybe ably projectsi laterally ybeyond the side and end walls so astoform an anchor'or -abutbottom view of the device lookment arrangementfor assistingin holding and securing lthe crete.

The upperchamber or recess 2 is to receive u the upper end of the boltor pipe or rod to device in positionv in the conbe supported by thedevice, a bolt 5 being shown in the. drawings for illustrating themethod of using the device. The upper end of this bolt 5 or bar or kpipeorother element -1 65 supported by the insert would project into therecess more o r less according to the eX- f tent to which the bolt orpipeentered the device and vertical adjustment of the same.

would be permitted bythis chamber 2.

A nut 6 for the bolt 5 is shown in the lower chamber 3, rIfhis chamber 3is preferably wider than the upperchamber 2,.with shoulV ders 7-7preferably formed on the side walls of the device for preventing the nut6 from l 75 entering the chamber 2 while permitting the end of the bolt,rod or pipe to enter said chainber 2. The bottom 8 of the device isprovided with an elongated slot 9 communicating with .i

. the lowerchamber 3. This slot 9 is suiliciently v-wide to readilyaccommodate the bolt 5 or, Y other similar" element and is alsopreferably of such width as to permit the nut 6 to be readilyinsertedorpushed through the slot 9 into ,the lower chamber 8 andthe latter is ofsuch j i turned ortilted as shown in Fig. 41 after said4 r nut has been.pushed through the slot9 as height andv size as'k to allow the nut 6 tobe shown in said figure.

The lowerchamber 3 also preferably has one port-ion as for example theportion 10 Vwhich is relatively narrow or contracted., bel ying onlyslightly wider than, the width of the `nutv6, as shown in Fig. 2, sothat said nut 6 cannot be turned or rotated in said chamber f vportion10.k Said chamber, however, has preferably another portion as 11Qwhichisjfy wider than the portionA 10 and of such width l as to permit nut 6to befturnedor rotatedin y r @said portion 11 as shownin Fig.v 2, nut .6be@ 1 ing shown in dotted lines in said ligure with-V in the portion11in aturned position., show'- ing it may turn completely laround insaidportionV 11. Said portions 10 and 11 may be variouslylocated but are lbypreference. arranged at the opposite ends of the chamber 3 '105 and atAmore Vor lessopposite ends of the def f, rviceas awhole. f

@ne end 12 of the.v device is preferably in?` placed so as to give it aninclination and thereby permit angular adjustment of bolt 5 or then thebolt 5 or like element may have its threaded end pushed through slot 9and screwed into nut 6. In some cases the article or device to beattached to bolt'5 or like element may then be fastened to or hunguponsaid member 5 in the manner desired with the nut 6 confined in portion10 of 'chamber 3 as shown in full lines in Fig. 2. In other casesangular adjustment of bolt 5 or similar part may be desired in whichcase said bolt 5 may be arranged as shown in Fig. 1. In other cases,however, it may be desired to turn bolt 5 or similar element after ithas been arranged in or connected to the insert, in order that someother threaded article or part may be secured by screwing to the lowerend' of -bolt 5 or pipe or bar secured to the insert as described inconnection with bolt 5. In these other cases it is apparent that aturning of bolt 5 or pipe or bar with the nut 6 held against rotation,might result in said member 5 being unscrewed out of the nut 6, thereby'disconnecting member 5 from nut 6 and destroying the connection so thatthe whole arrangement would fail of its purpose.. In order to avoid thiswhere so desiredto turn member 5 for further .screw threaded con?`nection, said member 'may be moved to the left referring toFigs. 1, 2,and 3, so that nut 6 will move out of chamber portion 10 into chamberportion 11 and when in this positionfelement 5 or the like maybe turnedor yrotated to any desired extent so that a screw threaded' connectionmaylbemade with another part'or article or hanging as desired.

After this threaded connection is made ther element 5 .may if desired beturned so that nut 6 may reenter channel or recess 10 and element 5maythen be. moved to cause such entry of nut 6*into channel 1() and thedevice may be left inv this Acondition in which element 5 will be firmlyand securely held in position and against rotation with screw threadedconnection at each end. l

It will be seen that while the nut or holding velement 6 is in itschamber 3 withthe supportingl member 'attached, said member 5vmaybejmoved back and forth longitudinally ofthe'd'evice to anv desiredextent in order to secure any adjustment of the holding element 5 to anyposition in which it is desired to place it, according to therequirements of the device to be supported. Furthermore, in

any such longitudinal position the member 5 may .bearranged at anyangularity desired for theaccommodat-ion of the device to be supl portedor the position of this device 1 in the concrete or other material inwhich it is to be set, and this longitudinal and angular adj ustabilityof member 5 is not interfered with in the least by the enlargement ll ofchamber 10, nor is there any likelihood of the nut or holding `element 6`becoming displaced 'or working loose by reason of such enlargement 11.Furthermore, if by reason of excessive loading or carelessness instarting member 5 into element 6 or for other reason the screw threadsare. spoiled or stripped, element 6 may be removed and a new oneinserted in its place. v i Y As a preferred arrangement a loop 14 issecured to the top 4 as by casting ,it integral with the rest of thedevice. This loopl has an aperture 15 to accommodate reenforcing rodswhere the weight to be supported issuch vas to make it unsafe to dependentirely upon the adherence to the concrete.

Also as a preferred arrangement the bottom 8 is provided with sideprojections V16 and 17 having recesses or notches 18 and 19 which isrelatively narrowto prevent turning of a holding element and the otherend of which in the same horizontal plane is rela-y tively wide topermit turning of said element.
